Three-phase voltage stabilizer Ampere U 12-3/40 v2.0 is designed to operate in three-phase electrical networks with voltage fluctuations from 145 to 275V. In this range, the device is guaranteed to deliver a voltage at the output within 220 ± 3.5%, which is ensured through the use of 12 stabilization steps. The total rated power of this model is 27 kW (9 kW per phase), which corresponds to the operating current of the 40A circuit breaker on it.
The features of this stabilizer include floor-standing design, independent operation of each of the phases, the presence of electronic transit (bypass), silent operation due to the use of thyristors as power switches.
Stabilizer Ampere U 12-3/40 v2.0 has the ability to manually adjust the lower shutdown threshold (60-135V). This function is in demand for a load with high inrush currents, at startup of which a strong voltage drop and emergency shutdown of the stabilizer are possible. When this option is activated, the stabilizer will make it possible to start any engine or pump within a minute, even if the voltage drops to 60V in the network.
It is recommended to install and operate the Ampere U 12-3/40 v2.0 stabilizer in dry and heated rooms. The connection is made to the existing wiring through the terminal block, which is located in the upper part of the housing under the cover.
